I've never been a fan of body lifts - I'd cut my cowl - or do anything else it takes to make this happen.



Someone else should run with the ball. Pacbrake R&D disappoints me a little.



Are any performance modifications cost effective for the consumer? Not really... Can they be made cost effective for the producer - you betcha.



Last time I checked, there are still plenty of people in line willing to spend $8k for a full billet automatic transmission. I know what the markup is for a lot of the diesel performance products out there... in some cases, it's still not as bad as furniture markups... but products can be made with a good margin.



I'm fully convinced it could be done if someone was willing to think outside the traditional design, develop, test and ship millions mentality.



This sort of product will never sell with the same kind of numbers that other products will... but whoever does it will forever burn their brand image into the memories of every dieselhead out there. That alone is priceless.



It's a leap of faith for sure... but I'm confident that this will happen someday.



Beers,



Matt

I'm no expert in exactly how they're produced, but I believe that there are Jakes out on the market that don't cover all six cylinders. In fact I was in a heavy duty wrecker once that had a two position toggle switch for the jake. One set it to work on two cylinders and the other on four. So if it isn't necessary to have it work on all six, then why couldn't it be designed to work on just the front 2 or 4 cylinders? This would avoid any problems with the cowl. Maybe too high for the hood, but it's a lot easier to put a different hood on than to raise the whole body.

They do make jakes for only four cylinders, I have buses that run only four cylinders because it would cut into the floor on the back two cylinders. On those engines they use the injector rocker arm to precisely time and pressurize the jake, that's how they can only run it on four. We can't do that with our engines because we don't have a cam lobe running a rocker arm to give pressure to a HEUI injector. If they were going to run jakes on our motors, they would have to find an intake or exhaust valve from another cylinder that would be opening very close to the same time as an injection event on another cylinder and use that to pressurize the oil passage for the jake to hold the exhaust valve open on that cylinder so they would have to run it across all 6 cylinders, even if they were only "jaking" four cylinders. Good idea, but not possible with our motors. If they could figure out a way to tap into a pressurized oil passage in the head and just use a solenoid to open that pressurized oil to the piston that will push and hold the exhaust valve open then a four cylinder setup might be doable. But I don't know if 40-60PSI of oil pressure would be enough pressure to push and hold an exhaust valve open. I've been wanting "jakes" on my motor since I bought it just because it would be awesome! But trying to figure out a way to make it work would be very difficult and I can understand why a company doesn't want to since that much money into R&D. I would imagine in the future the technology will be there to just put some kind of electromagnetic solenoids under the valve cover to push and hold open the exhaust valves. I would love to try some different ideas of trying to make one work, but I'm not a machinist and I don't have tons of money to sink into the idea.

I'd buy it in a heartbeat. Been researching on line about it for one year now. Disappointing that it is not available.

I thought about this for a while, and I think they need to look at older diesel engines that had mechanical injection pumps, no electronic injectors with a rocker arm pressurizing the injector, thereby giving you a place to add jakes. I. E. Cat 3208, 3406, Detroit 8V92, etc. They obviously figured out a way to put jakes on the older engines so they need to go back and look at those, and see if that kind of old technology could be used on our motors. The question still remains though, what about clearance in the rear, and what/where is there a place to actually bolt down the jakes to the top of the head? What kind of machine work would it take to give you some place to bolt them down? I think that could end up being the most expensive part of the whole deal.

Were do we mount this Jake there is no room under my hood for any mounting aft of engine the fire wall is in the way. Lift the vehicle that mite work but I already lifted the truck three inches, how abour putting hole in the hood or a hump in the hood.

Presently I have onboard air compressor, Warn winch controls, exhaust brake ,AFE total inclosed air filter housing there is no room left to mount.

The worst thing is that Dodge pickups are probably only 1/2 (if that) of the market. How many School Busses, Motorhomes, Skidders, Yardgoats, Medium duty trucks,ect. are out there w/ the 6bt? There is tons of applications that DO have room. Oh well I guess I'll have to be the one to design one and make my millions

 

[JesseJ]

I've been saying the same thing since I bought my truck back in '02, but I don't have any kind of machining capabilities. :-laf I think it could be done, but who has the money to do it? If the unit cost $2000 then I think the market would shrink significantly. It would have to be competitive w/ current exhaust brakes now, and that might be tough to do.

 

[EDankievitch]

I'm all for the an exaust break only reason I don't have one is the cost. My service breaks are lasting about 60,000 mi. I have to have the truck a long time to pay for the exaust beak kit. Now if you want me to test one on my truck for free... ..... Sign me up!

 

[earpster]

I have an exhaust brake on my personal truck, and an internal on my work truck [sterlingwith a C12]. I like the exhaust brake but would love the internal! Yes I would buy one.
